Rechecks apply for fertility readings only. At present; rechecks are free of charge ONLY if your previous prediction passed with no success.If your current cycle began in the month predicted, you would not be eligible for a recheck until a new cycle begins outwith the predicted month. If you do not have regular cycles due to a condition such as PCOS, you will be entitled to a recheck 4 weeks after the predicted month has passed (28th of the following month).
